You may be noticing that your cat is having issues with vomiting, diarrhea or excessive hairballs. Your feline pet may also be experiencing a decreased appetite. If any of these symptoms apply to your kitty then you may need to take steps to improve your pet’s digestive health.

Read on to learn more about probiotics, what they are and how they can help your feline companion have a healthier, happier tummy.

What is the Best Cat Probiotic?

What are Probiotics?

Cats, just like their owners, need to have a healthy balance of bacteria in their digestive system in order to properly process their food. This is where probiotics come in. They are the “good” bacteria that reside in the digestive tract.

Believe it or not, they are actually live microorganisms that aid in digestion and help prevent diseases in the gastrointestinal system. Usually, the presence of these “good” bacteria occurs naturally. However, there can be circumstances that cause your cat to have a deficiency of bacteria which leads to the vomiting and other intestinal discomforts. This is where you can help by providing your cat with healthy probiotic supplements.

How do Probiotics Help Your Cat?

When your cat has intestinal issues such as Irritable Bowel Disease (IBD), probiotics can help to return the natural balance of “good” and “bad” bacteria in the digestive tract. IBD is a condition that cats can develop over time. It is often the result of cats continuing to eat “food” that doesn’t agree with them.

By adding probiotic supplements to your cat’s diet, it can improve digestion, strengthen the immune system and put an end to diarrhea. This is accomplished by reseeding the intestines with the right kind of bacteria.

What Kind of Probiotics Can You Give Your Cat?

There are two types of probiotics that have proven beneficial to cats. They are Bifidobacterium and Enterococcus. These large and difficult to pronounce words are simply different strains of bacteria that serve different purposes in your cat’s digestive processes.

Bifidobacterium usually hangs out in your cat’s small intestine and is heavily involved with digestion. The Enterococcus strain spends most of its time in the colon and assists with the healthy formation of feces and the maintenance of colon health.

While it is safe to give your cats probiotics that contain other strains of bacteria, it is important to note that cats have unique digestive needs as compared to humans or other pets, such as dogs. Cats are naturally designed to be carnivorous and live best on protein and fats.

Humans and dogs are designed to be omnivores and can add vegetables and fruits to their diets. So when you need to give your cats a probiotic supplement make sure you are giving them the proper strains of bacteria that will best support their digestive system.

What Else Do You Look For in a Probiotic?

When it comes to probiotics, it’s all about the CFUs. CFU refers to Colony Forming Units and the higher the number the better. This term refers to the ability of a probiotic to form and maintain its numbers once inside your cat’s digestive system. The more viable bacteria that exist in a probiotic, the better it will be for your cat’s health. By viable we mean the ability for these bacteria to grow and multiply inside your cat.

By ensuring that you have the proper strains of bacteria along with the optimal colony forming units in your cat’s probiotic supplement is the key to improving digestion.

Are There Any Risks Associated with Probiotics?

As a general rule, there are no serious risks or side effects associated with the use of probiotics for cats or any other pets. The biggest concern is that the supplement industry for pets is not very tightly regulated. This means that pet owners will need to do their homework to ensure they are giving their pets a quality supplement that is actually providing benefit.

In order to find the probiotic supplement that works best for your cat may require trying several different types. Not all supplements are going to work for all cats. Just because your neighbor’s cat is getting great results from a certain supplement does not guarantee any results for your pet. Consult with your veterinarian, do your research and try different options until you find the one that works best for your kitty.

So How Do You Get Your Cat to Take Probiotics?

You may be having nightmares about trying to get your pets to take medicines in the past. We’ve all tried hiding pills inside treats hoping to trick our cats into swallowing them. Sometimes it works and sometimes not so much.

When it comes to probiotics, you do have some options. If you opt to go with a pill form, then you may have to go with the “hide it in a treat” method. However, there are probiotic supplements that come in a powder form that allow you to sprinkle it over their normal cat food. Just like the process to find the right probiotic supplement, you may have to try several different forms of the supplement to see which one your cat will actually swallow.

How Do I Know It’s Working?

This is an excellent question since you can’t actually see these tiny microorganisms that will be living inside your cat. The best way to determine if the probiotic is having any effect is a reduction in symptoms such as vomiting and diarrhea. Contrary to some beliefs, these two conditions are not normal for your cat or any other household pet and should not be allowed to continue for prolonged periods of time.

Another indicator that the probiotic supplement is working is a reduction in hairballs. If your cat is coughing up hairballs more than twice a month, then there is a good chance your pet is experiencing digestive issues.

Finally, when you are cleaning out the litter box, you can gauge how well your cat is handling the new supplement. You should notice a reduced volume of feces as well as improved texture. Better digestion will lead to less waste and healthier colon function.

What Probiotic Supplements Options Are Available?

While there are a large number of probiotic supplements on the market, here are some of the better options available. Again, you may have to try several to find the one that works best for your pet.
